A rigid sterilization container's filter retention plate is cracked. What is the correct course of action?
Answer: Replace the container immediately and remove it from service
A cracked retention plate cannot reliably secure the filter, compromising the sterile barrier; the container must be taken out of service for repair or replacement.
Which wrapping material is preferred for items to be sterilized using hydrogen peroxide gas plasma (VPHP)?
Answer: Non-woven polypropylene (spunbond) wrap
Cellulose-based materials (paper, muslin) absorb hydrogen peroxide and are incompatible with VPHP sterilization; non-woven polypropylene wraps are the correct choice.
What is the function of a Bowie-Dick test when performed on a pre-vacuum steam sterilizer?
Answer: Verifies the sterilizer's ability to remove air and penetrate porous loads
The Bowie-Dick test detects air removal and steam penetration failures in pre-vacuum sterilizers, which is critical for ensuring sterilant contact with porous loads.
Instruments with tungsten carbide inserts should be packaged in trays that include which of the following?
Answer: Silicone mats or foam inserts to prevent contact damage
Silicone or foam inserts protect delicate tungsten carbide inserts from impact damage during transport and sterilization cycles.
Which of the following best describes the 'square fold' (envelope fold) wrapping method?
Answer: Each corner of the wrap is brought to the center sequentially, creating a neat envelope-style fold
The envelope or square fold involves folding opposing corners sequentially to the center, producing a neat triangular flap opening that supports aseptic presentation.
What is the purpose of instrument stringers or locks used during tray assembly?
Answer: To hold ringed instruments open for proper sterilant penetration
Stringers hold ring-handled instruments in the open position so steam or other sterilants can penetrate the box locks and surfaces that would otherwise be shielded.
What risk does placing a wet pack into the sterile storage area present?
Answer: Moisture wicks microorganisms through packaging, compromising sterility
Residual moisture acts as a vehicle for microbial wicking through packaging materials, directly compromising the sterile barrier of the contents.
